ACCEL introduces true ceramic spark plug boots

Burnt spark-plug wires are the bane of anyone running headers on a performance vehicle. The extreme temperatures aftermarket headers radiate can quickly turn even the finest performance plug wires to junk if direct contact is made for too long, and thanks to the contortions of many of those headers, keeping the plug wires and the tubes separated is often an ongoing battle.

For a number of years, ACCEL has been offering its Extreme 9000 plug wires with ceramic-coated boots as a measure against header damage, and the design has proven effective, but the engineers felt they could do better. Now, the Extreme 9000 Ceramic series is available with ceramic boots — not a coating, but actual ceramic boots, with the consistency of porcelain, and good for a claimed 2,000 degrees F.

The new wires can be had with boots that are straight or angled at 90 degrees or 135 degrees, and all sets use ACCEL’s 8mm Ferro-Spiro core wire, itself rated at up to 600 degrees while also offering only 500 Ohms of resistance per foot and excellent suppression characteristics. Currently, all of the Extreme 9000 Ceramic wire sets are offered as universal sets, and will need to be cut to length and assembled at the distributor end, which maintains conventional rubber boots.
